You’re no idiot, of course. You know who the first president was and who penned the Declaration of Independence. Yet even though the country is young in the eyes of the rest of the world, the United States became a superpower in fewer than 200 years. But you don’t have to brush the dust off your textbooks to learn more! The Complete Idiot’s Guide to American History, Third Edition, will bring you up to date on the most important events and people that forged this country—and those that continue to do so today.

Look at a map that shows the north Pacific Ocean. You’ll find the Bering Sea, an arm of the Pacific bounded on the east by Alaska, on the south by the Aleutian Islands, and on the west by Siberia and the Kamchatka Peninsula. Near the north end of the Bering Sea is the Bering Strait, which, lying between Alaska and Siberia, connects the Bering Sea with the Chukchi Sea of the Arctic Ocean. At its narrowest, the strait is only 55 miles across, the shortest distance between the continents of North America and Asia. Fifty-five miles in icy cold water is a long swim, but not much of an ocean voyage. Historians believe that once upon a time, there wasn’t even that 55 miles of water between the continents.

A Stroll Across the Bering Sea

Several times during what paleontologists call the Quaternary Period—that’s their name for the last two million years—a “land bridge” emerged in the Bering and Chukchi Seas as the sea level dropped due to the expansion of the ice cap surrounding the North Pole. The theory is that anywhere from 10,000 to 45,000 years ago, human beings used the Bering land bridge to enter the New World, migrating from what is now northeast Asia to northwestern North America. Beringia, as the land bridge is sometimes called, disappeared when the major continental ice sheets and other glaciers melted, causing the sea level to rise again.

45,000 Years of American History (Abridged Version)

The trek across Beringia was not really an evening’s stroll. It must have consumed thousands of years. By 9000 B.C., it’s likely that the former Asians reached Patagonia, at the southern tip of South America. In between, in the area that is the present-day United States, the population of what we now call Native Americans may have reached 11 million.

These Native Americans, thinly distributed over a vast area in bands of a hundred or even fewer individuals, lived for thousands of years on the ragged edge of subsistence. They didn’t develop great cities, but, as nomads, wandered, hunted, and foraged together. Then, perhaps 9,000 years ago, some bands began to domesticate plants in order to supplement foraged and hunted food. By the beginning of the 16th century, when Europeans first made contact with Native Americans, they were cultivating maize, beans, and squash, as well as manioc, potatoes, and grains.

Agriculture fostered a more stable lifestyle than hunting and gathering, and the horticultural groups lived in tribes. Along with relatively stable sources of sustenance and substantial populations came more or less permanent houses organized into villages, usually led by a recognized chief.

The Anasazi

Living at a subsistence level, it’s not surprising that, within the area of the United States, the Native Americans left little material evidence of their ancient cultures. In the Southwest, archaeologists have identified a people they call the Anasazi (from a Navajo word meaning “the ancient ones”). The Anasazi appeared as early as 5500 B.C. and are also called the Basket Makers, because of the many skillfully woven baskets that have been discovered in sites associated with their culture. The Anasazi built communal dwellings consisting of wood and thatch, and even occupied shallow caves closed off with rocks. By A.D. 400-700, Anasazi communities evolved into collections of somewhat more sophisticated pit houses, built over shallow excavations. During the period of A.D. 700-1100, the Anasazi began building what Spanish invaders would later call pueblos (Spanish for “town” or “village” and also “people”). These were fantastic groupings of stone and adobe “apartment buildings,” cliff dwellings seemingly hewn out of lofty ledges, the most spectacular of which survive at Mesa Verde in southwest Colorado.

The Mound Builders

In the meantime, to the east, in a vast area stretching from the Appalachian Mountains to the eastern, edge of the prairies, and from the Great Lakes to the Gulf of Mexico, other Native Americans were building cultural monuments of a different kind. From about 1000 B.C. to after A.D. 1500, many different Indian societies constructed earthworks that modern archaeologists classify as burial mounds, platform or temple mounds (which served as the foundations for important public and private buildings), and circular and geometric ceremonial earthworks. Archaeologists further recognize two traditions among the mound-building cultures: the Woodland and the Mississippian.

The Woodland mounds were built in eastern North America from about 1000 B.C. to the beginning of the 18th century. The earliest were simple, enclosing only a few burials, but later mounds often reached 80 feet in height, took many years to construct, contained numerous burials, and even included log tombs. The largest and most elaborate of the mounds was built in southern Ohio by people of the Hopewell culture (named after mounds found near the Ohio hamlet of Hopewell).
